When in use, in the process of continuously screwing the nut, the upper surface of the arc sheet 1 is pressed downwards by the sealing ring 4 and the damping sheet 2 together, so that the arc sheet 1 and the surface of the firmware are mutually tightly pressed, in the initial pressing process, because the arc sheet 1 is an integrally formed inward sunken arc sheet, the end surface of the arc sheet is designed to be a thin sheet 13 horizontal to the firmware, when the arc sheet 13 is pressed, the thin sheet 13 is preferentially contacted with the firmware, the side of the thin sheet 13 is thin, and elastic deformation is easy to occur, meanwhile, because the anti-skid block 6 is an integrally formed trapezoidal plate with uneven thickness, when the bottom of the nut and the anti-skid block 6 mutually start to press and rub, the narrow plate 62 on the upper thick surface of the anti-skid block 6 is preferentially contacted, in the process of continuously screwing the nut, the inward sunken arc sheet in the arc sheet 1 starts to elastically deform, the effective contact area of the arc sheet 1 and the firmware is gradually horizontally spread, and simultaneously, the nut continuously clockwise presses the anti-skid block 6, the anti-skid block 6 extrudes the anti-skid sheet 3, the anti-skid sheet 3 is a thin steel plate with an arc concave inwards, the levelness of the anti-skid block 6 is changed, and meanwhile, the anti-skid block 6 is slightly elastically deformed, so that the anti-skid block 6 is fully contacted with the bottom of the nut;
compared with the prior art, referring to fig. 5, 6, 8 and 9, in the process of continuously screwing the nut, because the arc sheet 1 is an integrally formed inward-concave arc sheet, the end surface of the arc sheet is designed to be a sheet 13 horizontal to the firmware, when the nut is pressed, the sheet 13 is preferentially contacted with the firmware, the side of the sheet 13 is thin, elastic deformation is easy to occur, the extrusion to the surface of the firmware is reduced, and the surface of the firmware is well protected;
referring to fig. 2, 3, 5 and 13, since the anti-skid block 6 is an integrally formed trapezoidal plate with uneven thickness, when the bottom of the nut and the anti-skid block 6 start to perform clockwise extrusion friction with each other, the nut preferentially contacts the narrow plate 62 on the thick surface of the anti-skid block 6, the narrow plate 62 has higher thickness and narrower plate surface, so that when the nut is screwed down, the friction force between the nut and the anti-skid block 6 is reduced, the nut is convenient to turn, and simultaneously the tightening axial force generated by the screwing torque is reduced, and the possibility of expanding rings is reduced;
referring to fig. 5, 7, 8 and 10, in the process of continuously screwing the nut, the inner concave arc sheet in the arc sheet 1 starts to generate elastic deformation, and is gradually horizontally spread out to increase the effective contact area between the arc sheet 1 and the firmware, so that the contact area becomes larger, the pressing force can be better dispersed, and the damage of the arc sheet 1 to the surface of the firmware is reduced to a great extent;
referring to fig. 5, 6, 7, 8, 9, 10 and 11, the nut continuously clockwise extrudes the anti-slip block 6, the anti-slip block 6 extrudes the anti-slip block 3, the anti-slip block 3 is elastically deformed by a thin steel plate with an arc concave inwards, the levelness of the anti-slip block 6 is changed, meanwhile, the anti-slip block 6 is slightly elastically deformed, so that the wide plate 61 on the anti-slip block 6 is fully contacted with the bottom of the nut, the contact area between the anti-slip block 3 and the nut is increased, the friction force is increased, the supporting force between a part and a part is increased, the nut is prevented from falling off, and the friction force between the nut and the bolt is enhanced.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and the modifications or the substitutions do not cause the essence of the corresponding technical solutions to depart from the scope of the technical solutions of the embodiments of the present invention.
